lle it known that l, FRANK li. ll'lonmv, a r'ilizen of thtl llniied States, residing' in the rity ot' lvashington. Distrirt of tohuubia. have invented Certain new and useful lmprovenients in. .l`ype-ll'vriting Machines. ot which the following a speeitieation.

My invention relates to typewriting ma ehines. and in partieular to machines hav ing a vibrating; ribbon meelianisin and means for Shiftingy the platen. It is speeially designed to he used in connection with a b1- ehrome ribbon shift.

ln the Underwood front strike typewriter, a vibrator raises the ribbon in trout of the platen at eaeh stroke ot the type-bars. The Vibrator is Controlled by a universal frame, actuated by heels on the type-bars. and in the present invention may be actu ated thereby byeitlrer ot two pins which reciprocate with a braeket, head or housingon ther universal traine. These pinsv may be ar ranged on opposite sides of the vibrator. and may be. adapted to selectively enter holes in it at different distances from the pivot of the vibrator. whereby owing to the diil'erent leverage. one pin will ,give the vibrator a lgreater throw than the other. lYhen therefore. a striped ribbon is used. either the rop or the bottoni may be brouvfht between the 'type and platen. so that, ny having' the proper pin aetuate the viln'atru'` either desired color may be used. Keys are provided for shitting` the pins in the housingr so that the ribbon eolor may be readily controlled by the operator. The pins which aetuate the vibrator may move up and down in said housing with the platen shift rail. and so shift with the shiftingT vibrator which is pivoted on said platen shift rail.

One ad vantage of my invention is that the vibrator is positivelv moved with the platen shift mechanism, and that if the apparatus is clogged with dirt. it Cannot assume. any wrong position but Will remain locked in whatever position it- Inay he found.

Other features and advantages will hereinafter appear.

, ln the accompanying! drawings, Figure. 1 represents my invention applied to an lire derwood typewriter. and shows so much of the typewriter as is essential to understand my invention. Fig. Q is an enlarged view ot' the pins and partv of the shifting media- Speciilcation of Letters Patent.'

nism. Fig. 3 shows the parts in ser! ion with the platen rail raised. Fig. 4 .shows the parts in section with the platen rail in its normal position.

A typediar l is swung!l by a key. not shown. to Cause upper and lower ease type 2 to strike against a platen. not drown. through a ribbon 3. As said typebar rises. a heel 4 on it` strikes a bar 5 of a universal member *i to Control the esrclipena-nt. not shown, and to aetuate the vibrator T .so as to raise the ribbon shield and earry ribbon between the type and the platen. The vi brator 7 is pivoted at Sl on an arm lt) of the platen shift rail ll. and an arm t2 of said vibrator extends upwardly het weeu the walhy 13 and 14 ot an attuator for tht` ribbon. in the torni ot a housingY l5 fast on the universal bar tl.. The platen shiftl rail is arranged in the usual manner to raise the platen so that upper ease tvpe 2 will write on it. Said vibrator aetuated bv means of pins l?? and lil formingr part of a trame Q1, whieh pinsl extend through slots 20 in said housing or aetuator. and vibrahtor-- waroly and rearwardly with iid housing. The pins 18 and 19 are arranged respeetively to enter openings 1G and 17 in the extension l2 of the vibrator, and may be so arranged that one of said pins always engages with one of said openings. Said training Q1 also comprises a rod 2T riding in slots 28 in said housing, so that it. is always held alined by said housing or actuator, and it also romprises a slide 22 riding in the ogn-nin;l formed by two plates 22a. which plates move up and down with the platen shit't rail ll. It will therefore be seen that the piu trame 21 shifts with the platen shift rail. so that when upper ease type 2 write on the platen. l the ribl'ion 3 will be vibrated to the propr-r point in front of said type. Said plates 22% however. are notv fast on said shift rail but form an .extension of a link 11a, whieh eX- tension lies along Said shift rail. and is held thereon by a pin Q3 extendingla through a slot in said link lla. Said link may be moved longitudinally along said shift. rail by means of keys 24 through a shaft Q5 and roek arm 2, said rook arm havin;r a pin and slot. eonneetion with said link. From this it will be seen ythat when either of the keys Q4 de pressed, the rock arm Q5 will he swung' by them so as to shift said frame ill in the houslli tlt)

l o o ing' l5 b v means ol .i pin "Z" ilisl in said liauie, which pin-rides iii a slot Q2". formed in the upper plate 2.. Said slot 22 is so ,toiii'ied as to permit the slide 2Q to run easily between the plates 22"' as the universal frame vibrates it. It will be seen that whenever :i key 24 is depressed so as lo cause the pin I8 to enter the opening 16. the vibrator T ivill have its longer cud swung4 through a conii'iarativcly long arc, and so raise the ribbon 3 till the lower edge 3b thereof is at'the printingipoint; while if pin 1f) enters the opening 17, the free end of the vibrator swings through a much smaller arc, and so nioi es the carrier 8 'only suiliciently to raise the upper edge 3 of the ribbon to the printing point. The pins 18 and 19 are prefer-A ably tapered so as to easily enter the openings 16 and 17 if the extension 12 does not precisely aline With them. The link 11L may be carried at its end on the platen shiftrail .1.1, where it is slotted at 29 to receive a screw 30 entered in the support 31 of said shift rail. The pin and slot connection is arranged to give suHicient play to accommodate the movement of the platen shift rail 11.
